Facebook today announced Trending, a new section of the News Feed which offers a personalized list of topics that are currently popular or growing in popularity on the social network.

The company has experimented with trending stories and articles in the past, in order to combat Twitter and help its users to discover content that wouldn’t normally surface in their News Feed. In its latest incarnation, each topic has a keyword and a headline that explains why it should be of interest. Facebook has positioned it in the top right-hand corner of the screen and users can review more topics by selecting the ‘See More’ option.

Facebook says the list is personalized, based on topics or pages that you’re interested in, as well as keywords that are trending worldwide.

The feature is rolling out in “select countries” on the web and Facebook says it will begin testing the feature on mobile devices shortly. “As with other features, expect continuous improvements from us over time,” Chris Struhar, engineering manager for Facebook said.
